Walt Disney WorldOne Dumbo the Flying Elephant ride is up and running in the new Fantasyland, with a second due to open in July, along with a new queue area.

The largest expansion in Magic Kingdom history methodically marches toward completion.

As promised, the new Fantasyland at the Walt Disney World’s most popular theme park is opening in phases.

In March, the first of the two Dumbo the Flying Elephant attractions, as well The Great Goofini (a re-theming of the popular Barnstormer family roller coaster) kicked off the first phase of the new Fantasyland.

In July, according to Meg Crofton, president of Walt Disney Parks and Resorts Operations for the United States and France, three additional areas will debut.

The second Dumbo ride will open, as will the innovative no queue queue space — an interactive area that will serve both Dumbos and allow guests to entertain themselves without the stress of waiting on long lines before they board either of the rides.

Also, just in time for summer’s heat in central Florida, the Casey Jr. Splash ‘N’ Soak Station will be ready to refresh guests.

Walt Disney WorldUnder the Sea -- Journey of the Little Mermaid is scheduled to be open during the holiday season at Walt Disney World's Magic Kingdom.

Fantasyland openings planned for late autumn, just in time for Holidays 2012, include the much-anticipated Under the Sea — Journey of the Little Mermaid, Enchanted Tales with Belle, the Be Our Guest Restaurant, Gaston’s Tavern and Ariel’s Grotto.

The ambitious Seven Dwarfs Mine Train, featuring an innovative new ride system, is being targeted for a 2014 opening.

“Fantasyland is a place where a very special kind of memory is made,” Crofton said during a press briefing last Friday.

It’s a place “where children just old enough to understand the moment come in contact with princesses and heroes and meet their most beloved friends.

“We are excited about sharing our treasured stories in new ways and giving guests the opportunity to interact with their favorite characters like never before.”
